摘要：

设计一种新型钻石形超宽带天线, 该天线印刷在介电常数为4.4的FR4介质板上, 尺寸为26 mm×24 mm×0.8 mm. 设计过程中对天线辐射贴片进行两次优化, 并利用阶梯化接地板的方法对天线进行优化. 实验结果表明, 该天线可在2.0~14.5 GHz内实现电压驻波比VSWR≤2的带阻特性, 相对带宽为151%, 且具有结构简单和小形
化等优点, 可应用于各种超宽带(UWB)系统中.

Abstract:

A novel ultra\|wideband antenna with diamondshaped patch was designed and fed by a coplanar waveguide. The size of the substrate is 26 mm×24 mm×0.8 mm and the substrate material uses FR4 with a relative permitivity of 4.4. The patch was optimized twice by ground plant’s first order optimization. The simulated and experimental results demonstrate that the bandwidth (VSWR≤2) starts from 2.0 GHz up to 14.5 GHz and relative bandwidth comes to 151%. This diamondshaped UWB antenna has the advantages of simple structure and miniaturization that can be applied to various UWB systems.

Key words: ultrawideband, planar antenna, antenna optimization
